Chris it is not going to be a problem because you can not fit it to a Dead-eye.

They have changed the power to +35% so it is now possible to fit it to a Executioner.

Sure the damage bonus is not as good as the Fire support Platform M, +10% vs +25% but if kixeye has not fixed that accuracy above 100% still reduces target evade then that will easily make up for that. And the priority targeting is just a added bonus.
